Germplasm evaluation of the native cultivar “Torrontes Riojano” (Vitis vinífera L.) collected in the Northwest of Argentina
(2015)
The cultivar ‘Torrontés Riojano’ (Vitis vinifera L.) was derived from a cross of ‘Muscat of Alexandria’ and ‘Criolla Chica’. Its origin was probably not a directed cross in Mendoza Argentina during the colonial period. ...
Tamaño de la baya y calidad del vino : no es el destino sino el camino
(2014-01)
En las bayas de Vitis vinifera L. destinadas a la elaboración de vinos tintos, el llamado “paradigma del tamaño” (bayas grandes = mala calidad; bayas chicas = alta calidad) es generalmente aceptado. Sin embargo, el tamaño ...
Grapevine morphological shade acclimation is mediated by light quality whereas hydraulic shade acclimation is mediated by light intensity
(Elsevier, 2021-06)
Plants acclimate to shade by sensing light signals such as low photosynthetic active radiation (PAR), low blue light (BL) levels and low red-to-far red ratios (R:FR) trough plant photoreceptors cross talk. We previously ...
Changes in leaf stomatal conductance, petiole hydraulics and vessel morphology in grapevine (Vitis vinífera cv.Chasselas) under different light and irrigation regimes
(2017)
Hydraulic conductance and water transport in plants may be affected by environmental factors, which in turn regulate leaf gas exchange, plant growth and yield. In this study, we assessed the combined effects of radiation ...
ABA and GA 3 increase carbon allocation in different organs of grapevine plants by inducing accumulation of non-structural carbohydrates in leaves, enhancement of phloem area and expression of sugar transporters
(2016)
Grape quality for winemaking depends on sugar accumulation and metabolism in berries. Abscisic acid (ABA) and gibberellins (GAs) have been reported to control sugar allocation in economically important crops, although the ...
Non‐structural carbohydrates and sugar export in grapevine leaves exposed to different light regimes
(Wiley, 2020-11)
Light is a main environmental factor that determines leaf microclimate within the vine, as well as its photosynthesis and carbohydrate metabolism. This study aimed to examine the relationships between photosynthesis, ...
Leaf carbohydrate metabolism in Malbec grapevines : combined effects of regulated déficit irrigation and crop load
(2016)
Background and aims: Regulated deficit irrigation and crop load adjustment are viticultural practices used to improve grape and wine composition. Our objective was to evaluate the combined effect of irrigation and crop ...
Nucleotide sequence of key genes from the biosynthesis pathway of the major flavonoid in “Malbec” and “Cabernet Sauvignon”
(2015)
In red wines, important sensory attributes such as color and astringency are the result of the accumulation of anthocyanins, which are located in the berry skin (and in the pulp of teinturier cultivars). Each cultivar has ...
